SPECIFICATI N forming part of Letters Patent No. 706,749, dated August 12, 1902. Application filed November 4, 1899. Serial No. 735,774. (No model.)

To all whom it may concern:

Be it known that we, WILLIAM R. Fox and GLENN J. BARRETT, citizens of the United States, residing at the city of Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

This invention relates to improvements in type-writing machines.

The objects of this invention are, first, to provide an improved mechanism for controlling the feed-roll; second, to provide certain improvements in the paper-guide; third, to provide an improved means of supporting the paper-guide; fourth, to provide an improved construction of ribbon-guide, which serves also as an auxiliary guide for the paper; fifth, toprovide an improved means of supporting and shifting the platen; sixth, to provide an improved means of retaining the platen in its positions upon the carriage; seventh, to provide improvements in the means of retaining the carriage closely and securely upon its track or ways; eighth, to

provide improved means for controlling the escapement ofthe carriage-feed; ninth,'to provide improvements in the platen-scales for type-writers and means of supporting the same.

Further objectswill definitely appear. in the detailed description to follow.

We accomplish the objects of our invention by the devices and means described in this specification. The invention is clearly defined and pointed out in the claims.

The portions of a type-writer embodying our invention are clearly illustrated in the accompanying drawings, forming a part of this specification, in which Figure lis a plan view of the upper portion of atype-writer embodying the features of our invention. Fig. 2 is a detail-sectional plan view of the same portions'with the platen and a portion of the carriage broken away. Fig. 3 is a detail transverse sectional view of the portion appearing in Fig. 1,taken on a line corresponding to line 3 3 thereof. Fig. 4 is an enlarged detail View of the ribbon-guide and carriage-support, taken on a line corresponding to line 4 4 of Fig. 2. Fig. 5 is an enlarged detail view taken on a line corresponding to line 5 5 of Fig. 2. Fig. 6 is a detail view of the platen, adjacent parts, and the platen-scale, a portion of the feed-roll being broken away. Fig. 7 is a detail sectional end elevation of the carriage and platen with the platen in position for work, taken on a line corresponding to line 7 7 of Fig. 1. Fig. 8 is a detail sectional view on the same line as Fig. 7 with the platen swung forward for inspection. Fig. 9 is an enlarged detail sectional elevation of the platen and adjacent parts, taken ona line corresponding to lines 9 9 of Figs. 1, 6, and 10. Fig. 10 is an enlarged detail view of the paper-guide and portion ofthe rod carrying the same. Fig. 11 is an enlarged detail sectional view taken on line 11 11 of Fig. 10, showing the means ofv supporting the paper-guide upon its rod. Fig. 12 is a detail sectional view of the means of controlling the esoapement for the carriage, taken on line 12 12 of Fig. 1, taken on a line corresponding to line 13 13 of Fig. 6. Fig. 13 is an enlarged detail view of the pivotal or fulcrum connection of the lever for controlling the feed-roll. Fig. 14.- is an enlarged detail sectional elevation through the feed-roll and platen-scale, taken on a line corresponding to line 3 3 of Fig. 1.

In the drawings all of the sectional views are taken looking in the direction of the little arrows at the ends of the sectiondines, and similar letters of reference refer to similarparts throughout the several views.

Referring to the lettered parts of the drawings, A is the top plate of the main frame of a type-writing machine. Supported on this top plate, preferably by suitable legs or brackets, are the tracks or ways A A over which the carriage B reciprocates when the machine is in use. These ways are preferably provided with suitable ball-races, on which rest the transverse longitudinal sides of the carriage, which are also preferably provided with ball-races corresponding to those in the ways below. To retain the carriage in close contact with the balls in the ball-race or with the way beneath, we provide levers L L, pivoted to the back rail A by the pivots m. Rollers L are carried by the upper ends of the levers and rest in agroove or rabbet Lon the back rail of the carriage. Springs it are provided on pins 71, to hold the levers yieldingly in position. This prevents loose joints between the carriage and its ways and secures an even movement of the parts over each other, and consequently greatly assists in preserving the alinement. The platen O is supported on this carriage so that it can be shifted back and forth while the carriage is in motion to permit the use of the shift-key. The platen is also so constructed and supported that it can be tipped or rolled up for the inspection of the writing thereon by the user. To these ends the platen O is provided with a spindle 0, extending out at each end and provided with suitable knobs or knurls for rotating the same. The platen O is supported in suitable journal-bearings in a frame independent of the type-writer carriage. The frame consists of end pieces F and side pieces or rods D E, the rod D being toward the front of the machine in use and the rod E to the back. On the ends of the rod E are provided antifriction-rollers E, which travel on ways 02 transverse to the direction of the carriage B and serve also as a support for the back side of the platen-frame. The front ends of the side pieces F when the machine is in position for writing rest upon suitable shoulders on i the rock-shaft arms G.

A rock-shaft G is located in front of the platen-roll and is supported in suitable bearings on the carriage B. This rock-shaft is provided with upwardly-projecting arms G, carrying pivots a. Extending from the pivot a at each end of this rock-shaft are links F, which preferably connect by suitable journal-bearings to the spindle 0, though it must be clear that independent pivots might be provided on the end piece F in this connection.

At the center of the rock-shaft G is adownwardly-projectingarm G, containinganotch extending in the direction of the shaft. Supported on the top plate A is a rock-shaft H, having an upwardly-projecting longitudinal fin H, which engages the notch in the bracket G. An arm H is connected at the end of the rock-shaft H, and to this arm is connected a spring 1-, which holds the rock-shaft-H, wit it its tin H, normally in the rearward position. The spring 7' is located beneath this top plate A. A rod or connection D extends to or is in connection with a shift-key at the keyboard for shifting the platen back and forth transversely to the direction of the carriage. To insure that the platen willremain in either shifted position, we provide springs I,having antifriction-rollers I to rest upon the antifriction-rolls E to force them forward or back and tend to prevent their stopping in the center, thus insuring a full throw of the platen either forward or back and preserving the alinement of capitals and lower-case letters in printing, the springs I of course being secured to the carriage. The ways for the rollers E are horizontal at the points where the shift back and forth for printing different letters occurs. It then extends slightly downwardly toward the front, anda portion an is depressed to form a shoulder for retaining the antifriction-rollers E when moved to this position. A lever or handle N is preferably provided, secured to the front rod D for tipping the platen up, and this permits the rolls E to travel over the ways it until they drop into the depressions at n, which retains the platen securely in position atthis point. The object of shifting the platen in this way is to enable the easy inspection of the writing and access to the work for any purpose. The shifting of the platen in printingis made adjustable and is regulated by the screws ti, extending through brackets on the ends of the carriage, the same being so located as to contact with the spindle O of the platen and so adjust the same.

On the front rod D of the platen-frame we support the main paper-guide. This paperguide is made up of a portion M, struck up from sheet metal and curved substantially-to correspond with the curvature of the platen. This is pivoted to a spring M by a suitable pivot O at the center, which permits the paper-guide proper to adjust itselfevenly upon the roll and put an even pressure upon the paper for half the circumference of the roll, or thereabout. The spring M extends upwardly and is curved into a loop above the rod D, then extends downwardly at its forward end, and is conformed to a sleeve on the rod D. Ascrew or bolt textends through the loop portion of spring'M, and a thumb-nut If is on the outer end of the same, by which adjustment is secured to control the tension of the spring as desired. On the front side of the rod D is formed a key-seat D. Within this key-seat extends a curved spring D, which curves outwardly toward the center against the sleevej and the ends of which rest in the bottom of the key-seat. The spring M, the sleevej,and the spring D" are all united by the screw 76 therethrough. The thumbscrew 70 extends through the spring M and the sleevej to put pressure upon the spring D, if necessary, and also to serve as a handie to move the paper-guide back and forth on the rod D. A pair of the paper-guides is used on rolls of the ordinary length, though it is obvious that their number could be increased for long rolls, and it is also obvious that on short rolls a single guide will be sufficient.

Supported by the rod E to the rear of the platen-frame is the paper-roll R on its shaft R. This paper-roll is made up of short sections on suitable sleeves. It is supported in position by the arms lat each end thereof. These arms Z contain longitudinal slots. A lever P extends downward from the upper left-hand portion of the platen-roll and is pivotally connected to the shaft E and then extends parallel with the same through the slots in the arms l for the purpose of controlling said arms, and the opposite end is pivotally engaged in the rod E,near the hub of the righthand arm Z. A small ball a is formed on the end of the arm P for that purpose, as clearly appears in Fig. 13. A second arm P, with similarpivotal connection, is provided toward the opposite end of rod E. Springs Z are secured by suitable screws or other means to the inside of the rod E toward each end and extend upwardly into a loop and downwardly outside of the rod E and rest againstautifriction-rolls 'u at each end of shaft R. Screws Z" extend through the back portion of the springs into the rod E to adjust the tension on the paper-roll. The paper-shieldZ for guiding the paper into the machine is also secured to this rod E, and a small bail .e is provided above to guide the paper above and away from the operating mechanism. To the rod E is also secured the platen-scale S, the same being formed with downwardly-curved supporting-arms S,which are made of springs to hold the platen-scale S yieldingly in contact with the platenroll. Fingers S" are struck out of the arms S to serve as additional supports and guides for the paper, as clearly appears in Figs. 6 and 9, the structure of the paper-scalebeingidenticalatbothends. The arms S are arranged beyond the ends of the feed-roll R, and thus permit the feed-roll to be manipulated without disturbing the scale in any way. The scale also serves as a shield,

covering the feed-roll and preventing the same from coming in contact with the ribbon.

We provide an escapement with an oscillating rack-bar K and pawls for engaging the same similar in construction to that appearing in our United States Letters Patent No. 614,943, issued November 29, 1898, for type writing machines. We here provide an improved means of controlling the same, so that the carriage can be released and movedfreely back and forth, as desired. To accomplish this, we provide a lever J, pivoted ate on the back of the carriage, with ears formed downwardly to extend between the pawls, so that it can act upon the outer pawl or inner pawl to lift either off from the rack. We provide a guide f, forked in form, on the end of the carriage to guide the lever and put a spring f between it and thecarriage to force it outwardly, so that the actuating end ofthe lever is held normally out of engagement with the pawl g. The working end of the lever we guide by means of the fin J, extending into a slot or groove J in the plate U, to which the escapement-pawls are attached. This provides a very simple and efficient means by a lever in convenient reach in front of the machine for releasing the escapement inmoving. the carriage.

To the top plate A of the machine we socure the ribbon-guides T, which are formed of thin metal and properly corrugated for strength. W'e form a slot 'or notch T from the front side into the same, so that the rib bon may be easily inserted without throwing it through any openingin theguide. The central portions T serve as guides for the ribbon, and the fronts thereof at T are curved upwardly, as is clearly indicated in Figs. 2 and 3, and serve to guide paper comingin contact with the same up and out of the machine. This guide is supplemented by a downwardly-depending sheet-metal guide Q, secured to the front rail of the carriage. It is obvious the guides T would serve a very useful purpose were they not supplemented by this guideQ. These guides are of particular value where it is desired to address or write upon cards, as postal cards or narrow stiff paper. The springs M of the main paper-guide are the only ones in action under ordinary circumstances. These springs are, however, some distance apart, and therefore narrow strips of stiff paper, such as cards, are not positively guided. The guide T,with the part Q, is to supplement the main guide in such cases.

Having thus described the various parts in detail of our improved type-writing machine, we desire to state that the structures are capable of great variation in detail and form withoutdepartingfromourinvention. Where we have described the parts as constructed of sheetmetal, we desire to state thatthat is only the preferred construction and that the various parts might be formed of cast metal, of forgings, or otherwise. We have also shown the carriage provided with ballbearings, which is of course a very desirable feature; but we are aware that other bearings might be provided that would be quite effective in use. We have in certain instances described. certain forms of springs; but in many of these positions other forms could be used with equal success. At the ends of the platen-framewe have shown rollers for relieving the friction. It is obvious that while these are very effective for the.

purpose in the cheaper construction of ma chines they might be dispensed with. It is also obvious that many of the features which we have here described are adapted for use in type-writers of other constructions, and we do not wish to be understood to limit ourselves to a type-writer of this particular construction when We point out such features in the claims. Many of the features which We shall claim we consider to possess great merit in exactly the form shown, and therefore purpose to claim the same specifically in the form shown, as well as broadly. From these remarks it will be clear that there are many equivalent constructions which We embrace and contemplate in our invention.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-
